Description
The TLE4678 is a monolithic integrated low dropout fixed output voltage regulator for loads up to 200 mA. An input
voltage of up to 45 V is regulated to an output voltage of 5 V. The integrated reset and watchdog function, as well
as several protection circuits, combined with a wide operating temperature range offered by the TLE4678 make it
suitable for supplying microprocessor systems in automotive environments.
The watchdog circuitry will be disabled in case the output current drops below a programmable threshold, enabling
a microcontroller to switch in stand-by mode. Modifying the reset threshold is possible by an optional resistor
divider.
The TLE4678 is available in a PG-DSO-14 package which makes it pin-compatible to the TLE4278 as well as in
a small thermally enhanced PG-SSOP-14 exposed pad package.
